As Antiques and the Arts reports, the 40-year art mystery was solved when a lawyer contacted the FBI’s art crimes division in October that a client had a painting that didn’t belong to him that he wished to return.

The estimated value of the recovered painting is put at between $600,000 and $1 million, significantly more than its value at the time of theft.

The family returned the 1970s claims payment to Chubb in exchange for the painting. Chubb will donate the funds to Norman Rockwell Museum in Stockbridge, Massachusetts.

I.I.I. tip: A standard homeowners policy offers only limited coverage for high value items. If you have belongings that exceed these limits, you should consider supplementing your policy with a floater, a separate policy that provides additional insurance. Before purchasing a floater, the items covered must be professionally appraised. Don’t forget to add these belongings to your home inventory.
